Will the resection of pheochromocytoma improve preoperative diabetes mellitus?

Pheochromocytoma and glucoregulation disorders

“…However, rates close to 78% of resolution have been revealed by the studies by Beninato et al ., Stenström et al ., and Liu et al . [ 8 9 10 ] Finally, the lowest rate of resolution (14.8%) was reported by Sahli et al . [ 11 ]…”

“…Of the 23 patients, 26% had signs of diabetes mellitus, which is similar to the 12.41%–40% incidence reported by other series of patients with pheochromocytoma. [ 4 7 8 9 10 11 ] Regarding glucose intolerance, only a few series put the points on this subgroup, with a very variable prevalence reaching up to 71% in the study by Pogorzelski et al . [ 7 ] and only 5.22% in the series by Beninato et al .,[ 8 ] whereas the median observed in our study was 34.78% [ Table 2 ].…”

“…[ 8 ] Other studies did not find a positive relationship between BMI and the risk of diabetes. [ 4 10 ]…”

“…Hence, BMI might be the predictive factor on the resolution or improvement of postoperative diabetes among pheochromocytoma patients. [ 10 ]…”

“…However, in the Beninato and Liu series, the resolution of diabetes concerned patients with larger tumors and higher preoperative catecholamine levels, but not statistically. [ 8 10 ]…”
